For Structural Blast Design:
Plot the equation representing the (Dynamic deflection/Static Deflection) .vs. (t/td) (x axis) for values of (td/Tn) = 0.2, 0.4, 0.5, 0.8, 1.0. Present observations from the graphs regarding when the maximum dynamic deflection occurs and what is the maximum value of the ratio of dynamic/static deflection in each case. (You can attach an Excel file with each graph in a different sheet).
